(1.1.6)component in frame with focus doesn't keep focus when frame regains focus

Name: moC74494 Date: 05/21/98


Since 1.1.6, if the Java application (running in a Frame) loses focus
to any other window (doesn't matter if it's a Java Frame, another
Windows application, or even a Java Dialog), the component in the
Frame that had focus no longer retains that focus, as it had in
1.1.5 and earlier.

I noticed this problem on Windows, unsure if it's also in Solaris.

Here is sample code that puts three buttons in a Frame:

import java.awt.*;
public class test
{
      public test()
      {
Frame f = new Frame("focus test");
Panel p = new Panel();

p.add(new Button("button 1"));
p.add(new Button("button 2"));
p.add(new Button("button 3"));
f.add(p);

f.pack();
f.show();
      }
      public static void main(String[] argv)
      {
test t = new test();
      }
}


Click on either button2 or button3, and switch to another
window, then (without clicking a button) switch back to
the test frame. Button1 will now have focus.

We have an application that has a List box of items. When
you hit return on one of the items, a Dialog box appears and
allows you to edit the item. When you hit enter, we automatically
select the next item in the list. Since focus (in 1.1.5) remained
in the List component, the user can easily edit the next item in
the list just by tapping return. Now with 1.1.6, focus leaves the
List box and jumps up to the first button in our toolbar.

I know it's probably possible to set up a bunch of focus listeners
and stuff... but do I HAVE TO?? I'd rather it worked like it used
to.
